Epibenthos and demersal fish monitoring at long-term monitoring stations Trawl samples were taken within the disposal site and outside the disposal site (close neigbourhood) (classic controle/impact design). Sampling activities were in February-March and in September/October. A 8 meter shrimp beam trawl (22 mm mesh in the cod end) equipped with a bolder chain was used.The net was towed during 30 or 15 minutes at an average speed of 4 knots.

Epibenthos and demersal fish monitoring in function of dredge disposal monitoring

What ecological effects does a foreshore suppletion, and a beach suppletion, have on the marine ecosystem in the intertidal and shallow surf zone (&lt;6 m depth)? The foreshore suppletion (400.000m³) was by means of an experimental set-up in the shallow coastal zone (-1 to -2m TAW) of Mariakerke. Beside it, a beach nourishment was conducted at Mariakerke (681243m³) and Middelkerke (968754m³). For the Mariakerke area, we collect biological and sedimentological samples in the impact area and in a control area (Bredene), before as after the suppletion, whereas for Middelkerke only the data after suppletion was part of the study. We monitor the marine ecosystem with a focus on the fauna within the sediment (macrofauna) and on the sediment (hyperbenthos, epi- and demersal fish fauna) in the intertidal zone and subtidal zone.

Abiotic and biotic parameters measured in a field experiment to investigate the effect of predation by epibenthos on infaunal macrobenthos of a <i>Ceriops tagal</i> tropical mangrove monthly sampled between August 1992 and December 1992. The data were digitized by VLIZ from the original report: Garcia de Camargo, M. (1995). Interactions between macrobenthic epifauna and infauna in a Ceriops tagal mangrove at Gazi Bay, Kenya.

Species composition, density and biomass of epifauna in the creeks of saltmarshes Waarde and Saeftinghe between February and August 1991.

This database contains data on population characteristics of the hyper- and epibenthos, sampled in the Scheldt estuary, Belgian coastal waters and Belgian coastal harbours.
